Create a newUTexture2D'over' an existingUTexture2Dusing the same texture settings as a given sourceUTexture2D. This method only initializes the texture settings of ExistingTexture to match those of SourceTexture. To populate texture data, use Copy(..).
bool InitializeAndReplaceExistingTexture ( [UTexture2D](API\Runtime\Engine\Engine\UTexture2D) * ExistingTexture, [UTexture2D](API\Runtime\Engine\Engine\UTexture2D) * SourceTexture )
